APPARATUS FOR CLEANING wlNDows.

SPECIFICATION forming part of Letters Patent No. 708,854, datedSeptemberQ, 1902.

Application filed December 4, 1901. Serial No. 84,673. (No model.)

To all whom it may concern:

Be it known that I, HUGH BAIRD, a subject of the British King, residingatY Glasgow, in the county of Lanark, Scotland, have in venti edcert-ain new and useful Improvementsin Apparatus for Cleaning Windows;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention, which relates to apparatus for cleaning the outer sidesof window-panes, has for its object to simplify theconstruction of suchapparatus and to render it more efficient.

In order that my invention may be properly understood and readilyAcarried into effect, I have hereunto appended two explanatory sheets ofdrawings, in the several ngures of which corresponding parts are markedwith the same letters of reference.

Figurel is a side elevation of the apparatus embodying my inventionprojected through awindow and represents the apparatus in the operationof cleaning the panes of the upper sash. Both sashes of the window areshown insection. Fig. 2 is a backview of the same. Fig. 3 is apart-sectional viev'vr of the brush, brush-carrier, and guide-rod. Fig.4 is adiagrammatic View showing the arrangement of the cords foractuating the brush-carrier and imparting rotary motion to the brush.Fig. 5 is a front elevation of an apparatus used for cleaning the insideof Windows, walls, carpets, floors, and the like; and Fig. 6 is asideelevation of the same, all hereinafter more fully described. f"

In carrying my invention into practice with reference to Figs. l to 4L Iform the frame of the apparatus of two parts A and B, hinged, fixed, orotherwise secured to each other at right angles and, as shown in Fig. 1,provided with a pivotal pin b, by which the horizontal part B is capableof being folded up inthe direction indicated in dotted lines, thestationary horizontal portion B forming a table or frame. Above thistable rests the frame A, which when in use rests upon the window-sill Cby the leg D Aand antifrictional roller d, with which the end thereof isprovided, and to the portion A are secured the upwardly-projectingstandards or guiderods E and F for the box or carrier G, carrying thecylindrical brush or cleaner H, composed of short circumferential piecesof cloth or other soft textile material, which bears against thewindow-panes, as seen in the lastnamed figure. The horizontal portion Balso carries in suitable bracket-bearings I, Figs. land 2, at that endfarthest from the junction of the horizontal and vertical portions A andB aforesaid, a spindle J, on which is fitted a pulley K, around whichpasses the cord L for raising and lowering the brush 'nox or carrierG,the said spindle being driven by a crank and crank-handle M, fitted onthe end thereof. The end of the cord after passing around the pulley towhich it is secured in one of its grooves, of which there are two,passes under guide-pulleyj at the junction of the horizontal andvertical frames A and B, and thereafter being taken up over a pulley m,fitted to a cross-bar A', joining the vertical standards constitutingthe aforesaid brush box or carrier guides E and F at the top thereof,and down to a stud or pin Z, secured to the brush box or carrier G. Theother end of the cord O, secured to the pulley K in like manner to theaforesaid cord L, after passing under the guide-pulley lo, contiguous topulley j, is fastened to a stud or pin n, fastened to the brush box orcarrier G. By this arrangement the rotation of the driving-crank M`inthe direction of the arrow winds one portion of the cord onto thepulleyK, and so raises the brush box or carrier G. The reverse actionlowers it, as will be understood, and an equal portion of the ssY otherend of the cord L being unwound simultaneously. The brush or cleaner IIis fitted to rotate against a perforated plate P, formed of wire-clothand situated behind the brush I-I, through the meshes ofwhich the dirtis thus forced into a receptacle P'.

In the device for imparting rotation to the brushorr cleaner H, I attachone end of the cord Q to the brush-box G at g and take the cord up overthe pulley fm', mounted on the cross-bar A aforesaid, and then downunder two of the guide-pulleys p and q, mounted on the back of the brushbox or carrier G, andaround the pulley R, mounted on the spindle of thebrush or cleaner I-I, thence over a second scriesof guide-pulleys rands,

IOO

mount-ed also upon the back of the brush box or carrier, down under apnlleyt at the junction and up again to the brush box or carrier, towhich it is secured at u, the effect of which arrangement is such thatupon the brush box or carrier being raised or lowered the brush orcleaner is caused to rotate by frictional contact with the cord Q.

In that part of my invention illustrated in Figs. 5 and 6 speciallyapplicable to the cleaning of Walls and also applicable to the cleaningof carpets or ioors or the inside ot Windows or the outside of shop,church, or hall windows or for Washing paint I dispense with thehorizontal frame B and with the drivingpulley K and cords for raisingrand lowering the brush-box and secure the box G toV the one end of asingle vertical frame EQ which in such case serves also as a handle forpushing the brush box or carrier G' along the floor or up and down awall or window, one hand, holding the handle E2, being employed for thispurpose, the other actuating the cord, presently to be described. Thebrush H, contained within the box or carrier G aforesaid, is provided atone side with the pulley R', mounted on the brush-spindle, and isrotated by the frictional contact of a moving cord W. From the stud Q:of the sliding collar or bush V the aforesaid cord is led up to andpassed over a pulley o', thence through the guide-eye Q12 and around thepulley R' of the brush or cleaner H, which it is intended to rotate,back through the eye U3, over the pulley ful, and down to and under thelowermost pulley v5, and finally up to the stud or pin '116, mounted onthe aforesaid collar or bush V, which to effect the desired rotation ofthe brush in the cleaning operation is moved up and down the verticalframe bythe one hand of the operator. The vertical frame may in somecases be lengthened by ferrule-andsocket joints after the manner ofshing-rods and shown in dotted lines in Fig. 6.

I claim- 1. In a cleaning device, the combination With a rod and arevolnble brush mounted thereon, of a slide operating on said rod, andflexible means connecting said slide and brush for revolving said brushupon operating the slide.

2. In a cleaning device, the combination With a rod and a revolnblebrush thereon, of a perforated plate mounted behind said brush forcleaning the same, and a slide operating on said rod for revolving saidbrush.

3. In a cleaning device, the combination with the rod and brush thereon,of a slide operating on said rod, guides located adjacent said rod onopposite sides of said slide, and a flexible means engaging said brush,thence reeving through said guides and secured at its ends to said slidefor operating the brush upon moving the slide.

4. In a window-cleaning device, the combination with a rod and a slideoperating thereon, of a revolnble brush mounted on said slide, aperforated plate carried by said slide in engagement With said brush,means for operating said slide, and means operated by said slide forrevolving said brush.

5. In a Window-cleaning device, the combination With a rod and a slideoperating thereon, of a revolnble brush mounted on said slide, means foroperating said slide, guides located adjacent said rod,above and belowsaid slide, a flexible cord or tape secured at one end to said slidethence reeving through one of said guides to and around the axis of saidbrush, thence through the other of said guides and secured again to theopposite side of said slide, for operating the brush upon the upward ordownward movement of the slide.

In testimony whereof I affix my signature in presence of two Witnesses.

HUGH BAIRD.
